LIGHT DIFFUSER FOR I-IEADLllZGll-I'IS.

Application filed November This invention relates to reflectors, but more particularly to head light reflectors for automobiles.

An object of this invention is to producea'reflector for automobile headlights which is capable of providing maximum light for the road, but eliminates the blinding glare to approaching vehicles.

A furtherobject is to provide an auxiliary glare-eliminating reflector for automobile headlights. Other objects and advantages will hereinafter appear.

The invention is shown by way of illustration in the accompanying drawings, in which:

Fig. 1 is a front elevation of anautomobile' headlight with part of the lens broken away; Fig. 2 is a transverse sectional elevation of the lamp shown in Fig. 1';' and Fig. 3 is a side smaller than the main reflector, and isshown' as being held in place by the lamp 5, a central.

opening being formed inthe reflector to receive the lamp. The reflector 7 is of concave form and may be formed of material similar to the main reflector 2 having a'ninside reflecting surface. The auxiliary reflector 4 is formed with pairs of horizontal slits which provide vertical segments 8 and opposed side segments 9, the segments of each pair being substantially equal. As. mostclearly shown in Fig. 3, the segments 8 overlap the segments 9. and the several segments are turned or inclined inwardly toward the axis thereof.

It will be understood that the light rays emanating from the lamp 5 are reflected by the auxiliary reflector 7 in such a manner that the glare to approaching vehicles is elimi- 4, 1927. Serial No. 230,967.

nated, because the segments 8 direct the light .rays respectively downwardly and upwardly as well as sidewardly, at such an angle as to avoid the line of'vision of occupants in ap preaching vehicles. As shown in Fig. 3, the segments 8 are inclined inwardly approximately 30 froin the vertical, and the side Segments 9 are similarly inclined inwardly.

The various segments are bent along lines spaced from the central aperture provided in the reflector 7 to receive the lamp, the lines of bend being in juxtaposition to the main reflector 7 so as to be capable of engaging the reflector 7 to 1 hold the latter in position. It is to be understood that the light rays passing'beyond the auxiliary reflector 7 and impinging on the main reflector 2 are reflected outwardly, but as will be apparent to those skilled in this art, the glare from vehicle head lights is caused by that region incloseproximity to the lamp,so that-the remainder of the main reflector utilizes its full reflecting sur face away from theauxiliary reflector.

lVhile I haveshown and described the invention in connection with an auxiliary reflector having a definite number of segments, it is to be understood that the number and positioning of these segments maybe varied as desired. Other changes and modifications in details of arrangement and construction may be effected without departing from the spirit of the invention as defined in the ap-' pended claim.

' hat I claimas new and desire to secure by Letters Patent is: j V

An auxiliary reflector vtor use withheadlights having a main reflectorand an electricv lamp, composed of a body having a central openlng to receive the lamp and'having a plurality of alined horizontal slits located above the opening and a plurality of alined horizontal slits located below the opening to form elongated upper and lower segments and short intermediatesegments, the outer end parts of the segments being bent forwardly along lines connecting the slits.

In testimony whereof I have hereunto:

signed my name to this'specification.

I DONALD R FRUCHEY.
